How does an IGMP router maintain group memberships on a network? (Select 2 answers)
A broadcast and an NBMA network, each having two or more routers, must have both DR and BDR.
How many bits of the MAC address space is available for mapping IP multicast addresses?
An OSPF neighbor relationship fails to establish and the OSPF error information is displayed as follows. Which of the following is most likely the cause?
On a broadcast network or an NBMA network, not all neighbors need to set up adjacencies with each other. Therefore, the concept of establishing adjacency is applicable only to the broadcast network or the NBMA network.
Which of the following statements regarding the MED attribute are true? (Select 3 answers)
All routing protocols can deliver default routes, supporting both forcible delivery and non-forcible delivery.
How many multicast IP addresses can be represented by an IP multicast MAC address?

A company has four departments. Department A has SO PCs, Departments B and C both have 20 PCs, and Department D has 30 PCs. Assuming the IP address 192.168.1.0/x is used, which of the following statements are true if the VLSM technology is employed for subnetting? (Select 2 answers)
The most remarkable characteristic of OSPF is that it can support the link-state algorithm.
If the value of hold timers in the Open messages sent by Peer A and Peer B are 180s and 90s respectively, then what is the interval at which the Keepalive messages are sent after a BGP connection is established between these two peers?
Which of the following statements regarding ACL type are true? (Select 3 answers)
For link-state routing protocols, filtering inbound routes cannot block the transmission of link-state information. The filtering effect means that routes cannot be injected into the local routing table but neighbors can still receive complete route state information and calculate complete routes.
We can have different network segments in an OSPF area. We can also have same network segment in different OSPF areas.

Which of the following commands is used to display check information about the IGMP enabled interface?
A OSPF network may be structured, or subdivided into routing areas. Such routing areas are a set of network segments.
Generally, the performance of an IP-prefix-filter is greater than that of an ACL.
